摩擦摆支座的简化模拟方法OA
A simplified simulation method of friction pendulum bearings
为了进一步提高摩擦摆支座(FPB)的计算效率和模拟精度,提出了一种新的简化模拟方法.首先,基于FPB滑块的受力特点,研究了FPB的力学机理,并由此提出了由一个单摆和一根非线性弹簧构成的FPB简化模型;然后,通过对FPB简化模型进行受力分析,验证了简化模型基本力学机理与FPB的一致性;最后,选取了3条地震波对一块使用4个FPB隔震的混凝土板进行11个工况的振动台试验,采用简化模型对试验过程进行有限元模拟,并将试验分析结果和有限元分析结果进行对比.结…查看全部>>
In order to improve the computation efficiency and simulation accuracy, a novel simplified simulation method for friction pendulum bearing ( FPB) is proposed. The behavior of FPB was analyzed based on the stress characteristics of the slider of FPB. Then, a novel simplified FPB model with a single pendulum and a nonlinear spring was established. The mechanical behavior of the simplified model was analyzed and it conformed well to the basic requirements…查看全部>>
